SBIR-STTR Award

The realization of materials with record mechanical and electrical properties is of paramount importance to the Air Force and other branches of the US Armed Forces. Layer-by-layer (LBL) assembly is capable of producing nanocomposite materials with record properties surpassing those made by many traditional composite preparation techniques. However the process is time consuming and typically yields small and thin sheets of the composite. In this project we will achieve deposition acceleration by 100 times while retaining high conductivity of the deposited multilayers. In the LBL process we shall utilize carbon nanotubes (NTs) and special flexible polymers. The composite layers of polymer and NTs will be build-up on the substrate and then released for characterization with respect to structure. Record sizes of the samples of LBL composite material will be obtained. Large scale laminates will be made by consolidation of individual LBL sheets. The electrical and mechanical properties of the large scale coupons will be evaluated and optimized.
